The Lindisfarne Raid was the first known viking expedition to the West, and also the first raid on England. It was featured in Season 1 Episode 2 (Wrath of the Northmen). Done against Earl Haraldson's orders, the group sailed on Floki's new boat. It was led by Ragnar Lothbrok, together with Rollo and Floki, and among the raiders were Kauko, Erik, Leif, Arne and Torstein. The group totaled about 20 to 30 men. The group found a christian monastery filled with monks, one of them being Athelstan, who was captured as a slave. All the monks the ship could carry where captured as slaves (thralls) and the rest where murdered. Floki set fire to the scriptures of the monastery. The fire soon spread across all of the monastery.
